Chelsea boss Jose Mourinho remains in regular contact with Real Madrid president Florentino Perez.
The pair exchanged calls earlier this month as Mourinho offered Perez his support as Real battled for form.
Marca says the first call was made by the Real Madrid president to congratulate the club's former boss for Chelsea's Capital One Cup final win over Tottenham.
Mourinho made the second last Sunday after Real Madrid's away defeat to Athletic de Bilbao to congratulate the club president on his 68th birthday.
